Answer:
Packages A and C
Explanation:
To find the ratio between the number of lifts to the cost we first remove the $ symbol and find out how much 1 lift will cost per package.
Package A = 3 : 30
Package B = 5 : 60
Package C = 12 : 120
Package D = 16 : 120
Now let's break it down.
Package A = 30/3 = $10 per lift
Package B = 60/5 = $12 per lift
Package C = 120/12 = $10 per lift
Package D = 120/16 = 7.5 per lift
So now we are able to know which packages have the same ratio.
Package A and C cost $10 per lift.
